Vert.x is a toolkit for building reactive applications on the JVM. It's event driven, non blocking and polyglot, which makes it an excellent platform for building microservices. In this talk, I'll share experiences and from a Dutch company that started building reactive web applications with Vert.x about 3 years ago. You'll learn the concepts behind Vert.x, why we chose Vert.x, how we're using it and the challenges we faced. Topics include the anatomy of our projects, (micro)services architecture, deployment model and DevOps, scalability and the upgrade from Vert.x 2 to Vert.x 3.

- 1. Building microservices with Vert.x Bert Jan Schrijver AMSTERDAM 11-12 MAY 2016 @bjschrijver
- 2. Let’s meet Bert Jan Schrijver @bjschrijver
- 3. - Introduction - Why Vert.x? - Basic demo - Deep dive - Advanced demo - Microservices with Vert.x - Vert.x in practice Outline
- 4. - Introduction - Why Vert.x? - Deep dive - Demo - Microservices with Vert.x Introduction Malmberg is an educational publisher in the Netherlands. Malmberg is building modern, rich and scalable e-learning applications using Java 8, Vert.x, AngularJS and MongoDB, running on Amazon cloud services.
- 6. - Toolkit for building reactive applications on the JVM - General purpose application framework - Swiss army knife for building modern and scalable web apps - Event-driven, non-blocking - Polyglot - Lightweight and fast - Fun to work with! Vert.x: the basics
- 7. - We love open source - Powerful module system - Reactive characteristics Why did we choose Vert.x?
- 11. - Verticle, application, instance, JVM: Vert.x in depth Host JVM Vert.x instance Verticle Verticle Verticle Verticle Event Bus JVM Vert.x instance Verticle Verticle Verticle Verticle
- 12. - Verticle, application, instance, JVM: Host Vert.x in depth Host JVM Vert.x instance Verticle Verticle Verticle Verticle Event Bus JVM Vert.x instance Verticle Verticle Verticle Verticle
- 13. - Event driven and non blocking event loop - Multi-reactor pattern - Actor-like concurrency - Distributed event bus - Management and monitoring built-in Vert.x in depth
- 14. - Both request/response and publish/ subscribe - Messages are received by Handlers - All Vert.x instances have access to the event bus - Verticles interact using messages Vert.x event bus
- 15. - Never ever ever block the event loop - Need to to blocking stuff? Use a worker Vert.x’s golden rule

- 19. - Small in size, single responsibility - Runs in its own process - Has its own data store - Distributed by default - Independently develop, deploy, upgrade, scale - Potentially heterogeneous/polyglot - Light-weight communication Anatomy of a microservice
- 20. microserviceAnatomy of a Vert.x module - Small in size, single responsibility - Runs in its own process - Has its own data store - Distributed by default - Independently develop, deploy, upgrade, scale - Potentially heterogeneous/polyglot - Light-weight communication
- 22. - Organisation structure: - Core platform team (infrastructure) - Core modules team (Vert.x modules) - Product teams - Deployment model: AWS, Nginx, MongoDB - Multiple lightweight artifacts 3 years of Vert.x: situation
- 23. 3 years of Vert.x: deployments - Rolled our own deployment tooling and open sourced it (https://github.com/msoute/vertx-deploy-tools) - Controlled from Jenkins - Zero-downtime deployments - Microservice deployments
- 24. - Very suitable for test driven development - Integration tests with embedded MongoDB - Good cooperation from the Vert.x team 3 years of Vert.x: experiences
- 25. - Callback hell - Java 8 helped a LOT - Rx fixes the remaining issues - Blocking the event loop - Scaling / JVM overhead - Debugging - Static code analysis - Upgrade from Vert.x 2 to Vert.x 3 3 years of Vert.x: challenges
- 27. - Vert.x: toolkit for reactive applications on the JVM - Polyglot, event-driven - Very suitable for building microservices Summary
